RIVETING-MACI-IINE.

Specification of Letters Patent.

Application filed January 24, 1916. Serial No. 73,786.

To all whom it may concern Be it known that I, ARTHUR R. HAVENER, citizen of the United States, residing at WValtham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Riveting-Machines, of which the following is aspecification.

This invention relates to riveting machines wherein rivets are set in sheet material and also to machines in which rivets are set in sheet material and clenched in a rivet cap and furthermore to machines in which articles are fastened to sheet material by means of rivets and rivet caps. In machines of this character there are certain 00- casions when a rivet or-a rivet-cap, or several of them, may become jammed in and above the anvil and in such case, the anvil being located in a partially inaccessible position it is difficult to remove the rivet or rivet cap from the anvil.

The object of this invention is to provide means whereby the operator can move the anvil by hand to an easily accessible position, -whereupon the rivet or rivet cap may be removed from the anvil by the operator with ease.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

I have illustrated one embodiment of my invention in connection with a machine for attaching articles to sheet material by means of rivets which are clenched in rivet caps, said machine being substantially the same as a machine forming the subject-matter of an application for U. S. Letters Patent filed by me on September 27, 1915, Serial No. 52,816, and entitled Machine for attaching articles to sheet material.

Referring to the drawings: Figure 1 is a side elevation of a riveting machine embodying my invention. Fig. 2 is a central lon gitudinal section of the same. Fig. 3 is an enlarged sectional elevation taken on line 3-3 of Fig. 2. Fig. 1 is a sectional elevation taken on line 1- 1 of Fig.3.

Like numerals refer to like parts throughout the several views of the drawings. I

In the drawings 5 is the frame of the machine, 6 is a setting plunger which terminates at itsupper end in an anvil 7. The plunger 6 has a vertical reciprocatory motion imparted thereto by a lever 8, the forward end of which projects into a block 9 arranged to slide laterally of said plunger 6 in a slot 10. The lever 8 is adjustably fastened to a rock-shaft 11 by a set-screw 12, said rock-shaft being arranged to rock in bearings 13 provided in the frame 5 said lever having a rocking motion imparted thereto by a link 14, lever 15 and cam 16, the cam 16 being fast to a rotary shaft 17 and the lever 15 being pivoted at 18 to the frame of the machine.

The rivets are fed by suitable mechanism from a hopper 19 down a raceway 20 to a rivet carrier 21. A reciprocatory motionis imparted to the rivet carrier at suitable times by means of a lever 36, cam 37 and spring 38, said rivet carrier being supported upon a vertical slide 39.

The work is supportedon the work-support 22 and is held in position thereon by a presser foot 23 which is raised and lowered by suitable mechanism forming no part of this invention. Rivet caps are fed froma hopper 24 down a vertical raceway 25 along the horizontal raceway 26 to a position in line with the anvil7. The rivets are driven out of the carrier 21 through the material and riveted in the caps by a driver 27, which together with the rivet carrier 21, is oppositely disposed to the setting plunger 1 6 and anvil 7, the work-support 22 being located betweenthe setting instrumentalities and the anvil while the front end of the horizontally disposed raceway 26 terminates in line with the anvil 7 and beneath the work-support 22. A vertical reciprocatory motionis imparted to the driver 27 by a bell-crank lever 33, eccentric rod 34 and eccentric35 which is fastened to the shaft 17.

Patented'July 4., 1916.

The rivets are driven through the work which rests upon the work-support 22 and into a rivet cap which is carried up to the under side of the work and through an opening 28 in the work-support 22 by the plunger 6 and anvil 7. It will be seen that when a rivet or rivet cap becomes jammed or otherwise fixed inthe. upper end of the plunger 6 or in the forward end of the horizontal raceway 26, to remove such a rivet or cap from the upper end of the plunger 6 is a very difficult operation when the parts are in the position illustrated in Fig. 2 and if, on the contrary, the machine is turned so as to bring the plunger upwardly then at the same time the driver will be brought downwardly and will interfere with the removal of the rivet or rivet cap from the upper end of the plunger. Therefore, it is very desirable that the plunger 6 should be moved upwardlv while the driver and its mechanism remain stationary, and to do this a handle 29 is mounted upon the outer end of the rock-shaft 11, so that the rockshaft 11 can be rocked to impart a rocking movement to the lever 8 and a vertical reciprocatory movement to the plunger 6 at any time the rivets or rivet caps become jammed and the operator desires to remove the same by hand from the upper end of the plunger.

It is desirable that when the machine 18 running the handle should not be rocked with the rock-shaft 11 and the lever 8 and, therefore, to prevent this rocking movement of the handle a slot 30 is provided therein into which projects a pin 31 fast to the rockshaft 11. Under some of the conditions in practice the handle 29 can hang verticallv from the rock-shaft, as illustrated in F 1g. 1. In other cases the machine is placed on a bench and the handle 29 cannot hang vert cally but must assume a more or less horizontal position, and this is rendered possible by adjusting the rock shaft to different positions relatively to the lever 8. Sand rockshaft may be set in any desired position relatively to said lever 8 by means of the set-screw 12 which is loosened when it is desired to turn the handle to a horizontal position and then when set in the desired horizontal position the set-screw 12 is again tightened, leaving the rock-shaft free to rock during the operation of the machine without rocking the handle 29, however.

The general operation of the mechanism hereinbefore specifically described is as follows: The material 32 is placed upon the work-support 22 and the article to be riveted thereto is placed upon said material in the proper position to have a rivet driven through it and the material and clenched in a rivet cap on the under side of the material. The rivets are fed from the hopper 19 down the raceway 20 into the rivet carrier 21, while the rivet caps are fed from the hopper 24% down the raceway 25 and along the horizontal portion of the raceway to a position above the anvil. The plunger 6 is moved upwardly by the lever 8, link 14: and lever 15 to a position immediately beneath and in contact with the material 32. The material is held in position on the work-support by the presser foot 23. The rivet is brought down into position to be driven through the material and into the rivet cap by the rivet carrier 21 and is then driven through the material by the driver 27 which is operated by the bell-crank lever 33, eccentric rod 34 and eccentric 35, the rivet being clenched in a rivet cap beneath the material, said rivet cap being held in position during the clenching operation by the anvil 7 on the plunger 6.

It will be seen that while the machine is in operation the rocking of the shaft 11 does not rock the handle 29, as the pin 31 will rock backwardly and forwardl in the slot 30 without rocking the handle 29, but should any cap or rivet become lodged or fixed in position, due to a rivet missing be ing riveted in its rivet cap or due to the operator actuating the machine when the goods are not in position to have a rivet and cap set, then by stopping the machine in the position illustrated in Figs. 1 and 2 the operator can rock the handle 29 so as to engage the pin 31, thus rocking the rock-shaft 11 and'lever 8 to move the setting plunger ,6, together with the anvil 7, upwardly until the upper end of the plunger, with the anvil 7, is projected through the opening 28 in the worlesupport 22 and above the presser foot 23. ThEIGUPOIl the operator can readily remove any obstruction from the upper end of the anvil and upon releasing the handle 29 the parts will assume the relative positions illustrated in Fig. 1 and the machine is then in condition to be again operated to perform its various functions.
